LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 569,501, dated October13, 1896.

Application filed May 4, 1895. Serial No. 548,127. (No model.)

burn from the sides thereof and not directly.

at its upper edge, the same means being utilized to entirely close theannular wick-space between the wick-tubes in which the wick is arranged,so that the wick is prevented from smoking and all offensive vaporsarising therefrom after the light is extinguished prevented.

My invention consists, generally stated, in combining with thelamp-fount of a stationary interior wick-tube extending through thefount and supported entirely thereby at its lower end, a cap engagingwith the top of said stationary interior wick-tube, and a movableflame-regulating tube fitting around the stationary interior wick-tubeto form a wick-space, sliding directly on the wick, and adapted to openand close the wick-space between the cap and the top of the movableflame-regulating tube.

It also consists in certain other details of construction andcombination of parts, all of which will be more fully hereinafter setforth and claimed.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inWhich-- Figure 1 is a central section of a centraldraft lamp embodyingmy invention. Fig. is a central sectional view of the upper portion ofthe burner, showing the burner in its closed position. Fig. 3 is across-section in the line 3 3, Fig. 1. Fig. I is a detail view showingthe combined cap and flame-spreader removed. Fig. 5 is a centralsectional View of the upper portion of the burner, showing another formof my invention. Fig. 6 is a view of the cap shown in Fig. I removed;and Fig. 7 is a crosssection on the line 7 7, Fig. 5. Y Like lettershere indicate like parts in each of the figures of the drawings.

As illustrated in the drawings, A represents the fount of acentral-draft lamp having the flanged burner-base a secured in the topof the fount in any suitable manner. Rising from the top of theburner-base a is the foraminous skirt 1), which supplies the air to theburner directly from the exterior, as is customary in central-draftlamps. The foraminous skirt Z) supports the chimney-gallery 0 above thesame for holding the chimney c. Extending through the fount a andsecured therein is the stationary interior wick-tube d. The saidwick-tube d extends up into the burner and supplies air to the interiorof the flame, which is evolved from.

the exterior of the wick, as will be hereinafter described.

Mounted on the upper end of the interior -wick-tube (Z is a suitableannular cap and and a perforated flame-spreader 6 above the same, havingits sides flaring, as at 6 \Vhen the wick fis properly inserted over theinterior wick-tube d, the top edge of the wick f abuts against the lowersurface of the annular ring or shoulder 6 so protecting and holding fromdisplacement the raw edge of the wick.

Mounted to slide loosely around the interior wick-tube (Z on the wick fis the flameregulating tube g, provided with suitable means for raisingand lowering it, which, with the interior wick-tube (Z, forms theannular wick-space f for the wickf. side of the burner-base a is aninclined or spiral slot h, through which. extends from theflame-regulating tube g a suitable operating-handle h, whereby theflame-regulating tube g may, by the lateral movement of the handle h, beaxially rotated, so to lower or raise the same to permit the wick to belighted or to extinguish the flame, as the case may be.

At one In the use and operation of the lamp-burner, I

the parts being adjusted as shown in Fig. 1, the lamp may be lighted,the flame issuing from the exterior or side of the wick adjacent to thetop and not from the top edge thereof. The size of the flame isregulated by the position of the flame-regulating tube 9, the latterbeing raised and lowered by' means of the operating-handle 72, attachedthereto. When it is desired to extinguish the flame, theflame-regulating tube g is raised to its highest point, where, impingingby its top edge against the under surface of the ring or shoulder 2 itis stopped, the flame or burning space between the annular ring orshoulder e and the top edge of the flameregulating tube 9 beingcompletely closed to prevent the rising of the smoke and noxious vaporsfrom the wick, which accompany the extinguishing of the flame of theordinary lamp.

To renew the wick or clean the lamp, the combined cap and flame-spreadere is first taken off from the interior wick-tube cl, after which thewick f can be removed and the burner-base a disconnected from the fountA, said parts being replaced after the wick has been renewed or the lampcleaned in the inverse order named.

In Figs. 5, .6, and 7 another form of my invention is shown in which theflame-spreader is formed separate from the cap. In this case the flamespreader or deflector i is supported above the burner by means of a posti, projecting axially from the fixed interior wick-tube, said post beingremovably anchored in a spider-frame or other suitable support 2' in theinterior of said tube. The open spider-frame permits the air passing up.through to be supplied to the burner and at the same time afiords asupport for the deflector i. To renew the wick or clean the lamp in thisconstruction, the deflector 2' is removed from its spider=frame supportF,

then the cap taken oif the interior wick-tube cl, then the wick f, andthen the burner-base a taken out of the fount A. After the wick isrenewed or the lamp cleaned the parts are replaced in the inverse ordernamed.

Practical experience has proven that the lamp. constructed with theburner here claimed makes a far better flame than the ordinarycentral-draft lalnp. It burns all the oil that it raises and also thegases, overcomes the charring of the wick, and consumes all the gasesgenerated between the tubes. The oil never becomes heated and lastslonger than in the common forms of these lamps on account of thethorough consumption of the gases. The flame is, of a whiter color, thewick will last much longer, (generally about eighty or one hundred hourswithout trimming) does not require slitting at the bottom in order tofit around theconi-mon wick-raising mechanism, rendering it morelasting, and can be put on and-taken ed by any person, as it will notcome in contact with any interfering wick=raising mechanism so common inthis class of lamps.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is
